CONVERTIBLE Sora,

Application led yOctober 25, 1922. Serial No. 596,772,

To all whom t may concern:

Be it known that I, SALVADOR BARRILE, a citizen of the United States, residing at Medford, county of Middlesex, State of Massachusetts, have invented a certain new and useful Improvement in Convertible Sofas, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to a new and useful improvement in convert-ible sofas which are adapted to be converted from a'sofa into a bed. It is more especially intended for use in that class of sofas which are termed davenports, having a drop back so that the seat and back of the sofa together will form a bed of the width equal Vto the width of the seat and the height of the back, the headboard' being formed as a part of one end of the sofa'. y

In convertible bed Sofas heretofore made an objectionhas beenthat when the back is dropped down there is a gap between that portion of the bed formed by the upholstered back and the portion which is formed by the seat of the sofa. One object of the present invention is to provide such a yconstruction that when the back is dropped down to form the bed, the upholstered portion of the back will come as close to the upholstered portion of the seat as the two members of a two-part mattress of an ordinary bed. Another object of the invention is to provide mechanism of easy manipulation for dropping the` back when it is desired to convert the sofa into a bed. Other features of the invention will be more particularly set `forth in the specification and in the claims hereinafter.

The invention will be fully understood from the following description when taken in connection with the accompanying drawings, and the novel features thereof will be pointed out and clearly defined in the claims at the close of this specification.

In the drawings, Fig. 1 is a front ele.- vation of a sofa Vembodying the invention,

the upholstery being removed for, the purpose of more plainly showing the inside mechanism. p f. f v

Fig. 2 is a perspective view Showingk one end and a portion of the back of the article, as Shown in Fig. 1.

Fig. 3 is a Section on line 3,-3 of Fig. 2 on a larger scale.

Fig. 4 is an end view ofthe sofa with the upholstered seat and back in place but partly broken away to sho-w the mechanism for dropping the back. y Fig. 5 is an end view showing the parts of 4 but with the back in the droppeddown position to convert it into a bed.

Referring nowto the drawings, 1 andv 2 represent respectively the front and rear rails of the framework for supporting they seat of the sofa, and Jr-3 the lower end rails of the framework which connect the.

front and rear rails`12 at each end therei of. The framework also has the front and rearposts 4, 5 at each end, which at their lower ends are connected by the end rail 3 and are yalso connected by the arm rails 6. Anv end panel board 15 is attached to the said Venol rails. The back comprises a framework having two vertical endI rails 7, 7 and the top and bottom rails 8 9. The back framework isalsol preferably provided with intermediate verticalk bars 10-10 to divide the back portion of the frame into panels and stiften the frame. These panels 4are adapted to receive the upholstered back members` 11 and thel Seat receives upholstered cushions 12. Aheadboard 13 is longitudinally slidable on the ledge 14 for the purpose of extending the headboard of thebed when the back is folded down, as will be hereinafter explained. When said headboard 13 slides back, it will form a rear extension of the end board 15 which willv form the front part of the headboard.

A Segment gear 16 which is preferably substantially a quadrant is made fast to the upright end rail`7 ofthe back frame as Shown in Figures 4 and 5, byl any suitable means, the means shown being screws 17-17. The back frame together with the segment gear 16 is pivoted at 18 to the slide plate 21 at each end of the sofa, it being understood that each end of the sofa is constructed similar to the end shown in Figure 2, andthat there is a corresponding segment gear and other operatingmechanism, as will be hereinafter described, at each end.

A plate 19 is made faston the upper edge of the lower end rail 3 and has on its upper face a toothed rack 20. A slide plate 21 is formed with a longitudinal slot y22 and is supported bythe plate 19 by means ofthe engagement of the plate 19 with the longiof greater length than the plate 19 so that the slide plate is capable of a longitudinal movement, the plate 19 serving as a.traelr. A train of gears 2,4, 2,5, 26 is journalled in said plate 21, the gear 26 at one end of the train engaging with the teeth of the segment gear 16, and the gear 24 at the other end of the train engaging with the teeth of the rack 20. The plate 27 is secured to the bottom end rail 3, as by screws 28-28, and is formed with a grooved guide portion29. The slide plate 2l is formed with a fin or flange 30 which engages in the groove of the grooved portion 29 to aid in supporting and guiding` the slide plate 21, thus aiding the rack plate 19 in supporting the slide plate.

Means are provided for retaining the sofa back in its upright position when the sofa is to be used merely as a sofa and not as a bed, but which can be released to allow the back to be turned down.

Any suitable means may be provided for `that purpose. Tha-t shown in the drawings is as follows A slide bolt 31 passes slidably through a hole in the upright end 7 of the back frame of the sofa and is adapted to engage with slot l32 in a blocl 33 mounted on the top of the rear end post 5. Said'bolt also passes through a hole in the downwardly depending hanger 34 secured to the top back rail 8. A spring 36 coiled around the said bolt and having one end abutting against the end back rail y 7 and its other end abutting against, the said hanger 84, normally holds the boltv in the slot 82, so as to hold the sofa back in its upright position. oranl?. shaft 37 is pivotally mounted at 3S in a bearing on the under side of the back top rail 8, the said crank shaft being rotatable on its anis and is provided with a crank arm 39 so that it may be turned by hand. Mounted on the upright arm of said crank shaft 37 is a disk 40.vk The bolt4 31 has a downwardly dependn ing arm 41 at its end which engages with a hole in said disk 40.` TWhen said crank shaft 57, is turned on its axis the disk 4() will be rotated in a horizontal plane, thereby eaus ing the bolt 31 to be retracted and disenvfaged from engagement with the slot 32, leaving the entire back frame to dro) back. "ihere is also a locking` bolt 36 for the opposite end of the back, and means are provided whereby both bolts will be operated together by means of the crank 39. The means provided are as follows The said locking bolt consists of a rod 35 which passes loosely through a downwardly dependinghanger 42 secured to the top back rail 8, said rod 35 having a downwardly depending finger 43 which engages with. a hole in the disk40. The other end of said rod 35 passes through a holein the right hand end rail 7 of the back and engages with a sockety in a block 33 at the top of the right hand rear ost 5. See F i0. l. When the crank is turned to release the bolt 31, the rod is dropped down to convert the sofa into a bed will serve as legs. As shown in the drawings, each of the end bars 7 of the back has a folding leg 44 pivotally connected therewith at 45, the said leg liieing opened out to stand on the floor when the sofa back is folded down, said legs 44 being of sutlicient length to hold .the sofa back when turned down into its horizontal position at the same level as the seat portion of the sofa. A link 46 is pivotally connected at one end to the said leg 44 and at its other end to the post 5 of the sofa, so as to maintain the folding leg 44 against spreading when the sofais converted into a bed, as shown in Figure 5.

lhen it is desired to Convert the sofa into a bed, the crank arm 39 will be turned so as to rotate the crank shaft 40 and thus release the bolts at each end of the haelt from locking engagement with the sockets in the rear posts 5. The back will then be easily turned down on its pivots 1S at its opposite'ends, the back being allowed to drop down into horizontal position. The turning down of the sofa back on its pivots will also partially rotate the segment gears 16 through an angle of about 90 degrees from the position shown in Figures 2 and 4 into the position shown in Figure 5. This will give rotation to the train of gears 26, 25 and 24. ris previously stated, the teeth of the gear 24 mesh with the teeth of the rack 2O.v

inasmuch as the rack is stationary and the plate 21 on which the train of gears is mountedis slidable, the effect of the rotation of the gear 24 will be to cause the plate 21 to slide forward in its guides, and the folding legs 44 will be turned down into the upright position as shown in Figure 5, limiting the drop of the sofa back so that the said sofa back will be in the same plane as the seat of the sofa.

The forward sliding movement of the plate 21 will bring the lower edge of the upholstered sofa baek slightly forward when thebaek is turned down so that when it comes down into horizontal position the then forward edge of the upholstered back 11, which before the back wasturned down was at the bottom as shown in Figure 4, will be drawn forward into flush kengageznmt with the rear edge of thel seat cushion 12. If it were not for this forward movement of the sofa back there would be a gap between the two upholstered members l1 and 12. The headboard extension 13 will then be pulled backward by hand. The headboard is shown as provided with a finger vhole 49 for that purpose.
